Description
Technical field
The invention belongs to electrically conductive ink field, particularly relate to a kind of Nano silver conductive ink and preparation method thereof.
Background technology
Conductive ink refers to and is printed on conduction stock, and making it the ink having conduction current and get rid of accumulate static charge ability, is generally be imprinted on the non-conductive stocks such as plastics, glass, pottery or cardboard.Electrically conductive ink has to a certain degree conduction property, can be used as the use of printing conductiving point or conducting wire.The printing process of conductive ink is very wide, as silk screen printing, letterpress, flexographic printing, intaglio printing and planography etc.Can select different printing processes according to the requirement of thickness, thickness difference then its resistance, Solder resistance and rub resistance etc. is also different.Ink has thick film mill base and resin type two kinds, and the former is that the high temperature of tamanori burns till type with frit, and the latter take synthetic resins as the cryodrying of tamanori or the silk-screen ink of radiation (UV, EB) curing.
At present; the ITO conducting wire for having etched of the visible area of touch-screen; existing printed form conductive silver paste is essentially opaque silver grey property or canescence; silver powder is micron particles or flap-type; in this oleaginous system silver slurry, the content of argent is 40-75%; the consumption of noble silver is more, cost is high, does not also have silver powder content to account for the transparent wire reticulated printing conductive silver paste of total ink less than 5% at present.
